Hi9204 from Hichips(智芯), in a SOT23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BST | passive | Bootstrap capacitor connection for the high-side gate drive; absolute maximum voltage is -0.3 to 100 V. |
| 2 | GND | power_in | Chip ground reference; the datasheet gives no separate limit for this pin beyond the all-other-pins absolute maximum of -0.3 to 6 V. |
| 3 | FB | input | Output voltage sense feedback input that sets VOUT through external divider resistors against a 0.816 V reference; absolute maximum is -0.3 to 6 V. |
| 4 | EN | input | Enable pin; pull up to VIN through a resistor to start the chip, and pull low to shut off the output (off-state current below 0.1 µA). |
| 5 | VIN | power_in | Supply input with a 5 to 70 V operating range; absolute maximum voltage is -0.3 to 100 V. |
| 6 | SW | output | Switching node at the source of the internal power MOSFET; absolute maximum voltage is -0.3 to 100 V. |
